Answer:
You get two, (0,-3) and (1,0)
<u>Answer:</u>
Zero
<u>Step-by-step explanation:</u>
We are given the following expression and we are to determine what is the sign of its product:

One of the three terms in the expression is positive while one is negative. So if we start multiplying the two terms from the left side. we will get a negative number.
But when we will multiply it with zero, the whole product will become zero as anything times zero is always zero. Therefore, answer will be zero.
4x+3x=7x
18 girls-5%
Total no: of girlsx5/100=18
Total-100x18/5-360 girls
4x+3607x
360-7x-4x
360-3x
x=360/3-120
4x=4x120=480
3x=3x120=360
Total no: of students=480+360-840
He does not divide the numerator and the denominator by the same number. Nicholas divides 20 by 5 and 30 by 6. He ought to have divided 30 by 5 as well and then simplified.
P.S. Nicholas should have just divided both 20 and 30 by 10 to simplify in one step.
